Abstract
In this study we consider the multiple scattering of time-harmonic elastic waves in a metal matrix composite containing randomly distributed particles with graded interfacial layers. Both continuously and multilayered graded interface layers can be designed and evaluated. The method of solution consists of first solving the scattering problem by a large number N of arbitrarily distributed particles in an infinite matrix, the resulting equations are then averaged by considering the positions of the particles and solved by using Lax's quasicrystalline approximation. Numerical calculations for a SiC-particle-reinforced Al composite are carried out for a moderately wide range of frequencies and the effects of graded interface layers on the physical properties are shown graphically.
